Detailed Description

In an embodiment, as shown in fig. 3 to 5, an EPB switch toggle structure includes a housing 1, a circuit board 3 mounted in the housing 1, and a micro switch 4 disposed on the circuit board 3. Be provided with the button 2 that dials that can stir on the casing 1, concrete structure is: the two sides of the dial button 2 are provided with rotating mounting holes 22, the shell 1 is provided with a rotating pin (not marked in the figure) matched with the rotating mounting holes 22, the rotating mounting holes 22 are mounted on the rotating pin and rotate around the rotating pin, and one end of the dial button is pressed down or lifted up to enable the dial button to rotate around the rotating pin.

Two pressing ejector rods 5 are arranged on the lower portion of the dial button 2 in the front and back direction along the axis direction (namely the axial direction of the rotating pin) of the dial button 2, a micro switch 4 is arranged under each pressing ejector rod 5, and the pressing ejector rods 5 directly and vertically act on a trigger button of the micro switch 4 to control the on-off of the micro switch 4.

The upper end of the pressing ejector rod 5 is provided with a track end 51, the dial button 2 is provided with two tracks 21 matched with the track end 51, each track 21 comprises a track plane 211 and a track inclined plane 212, the pressing ejector rod 5 is pressed down under the action of the track inclined plane 212 to achieve the conduction of the microswitch 4, when the track end 51 of the pressing ejector rod 5 is matched with the track plane 211, the pressing ejector rod 5 is not stressed, and the microswitch 4 is in a disconnected state.
